Carpenter Technology interview questions

I went through a series of four virtual interviews and one on-site interview. I emailed each interviewer personally to thank them for their time and share my appreciation for the specific conversations that were had. They reassured me that it is not normally so intensive and that they were very impressed with my qualifications but at the end of this drawn out process they chose a different candidate without notice. When they didn’t reach out after my on-site interview, I called and emailed them to reiterate my interest in working with them at which point they informed me of their decision not to move forward with my application. All said and done it was extremely taxing and disappointing.
